reading battery voltage using nrf51822

[kvrb]

Hi, I am working on reading battery voltage of nRF51822 Microcontroller.

I have used the openbecon(internet) code for ADC configuration and reading.

I am getting 28 or 27 as ADC output.

is there any mistake in the code..?? I have modified and compiled the code.

main.c

Hi Kvrb,

I have created an example that measures the VDD of the nRF51822 from the template project in SDK v11.0.0.

I have attached the Keil project below, just extract it to nRF5_SDK_v11_0_0\examples\peripheral and you should be able to compile it.

Keil Project: adc_vdd_measurement_example.zip

Best regards
